Just because they're 100% cotton doesn't mean they're too thick to wear any time but the winter. Flannel should be left to the colder months, but flannel is a special type of thick, loosely-spun, fuzzy, soft fabric, often wool or cotton. Kilts and pajamas are often flannel, if that helps.There's nothing inherently wrong with wearing those shirts with chinos or cargos, but you're getting into nerd/dad territory with those choices. It's as much about the individual pieces...

Shout out to Kyle and the Everlane team for great customer service. There was a problem with a recent order of mine, but they worked with me to fix the problem. The tees need more taper, but the customer service is spot-on.

The gats I just got from Zeemon are too tight in the toes. If I get a size larger, will the toes be any less tight, or will they just be longer? Anyone have any experience?
EDIT: I have a wide foot, which may be the problem. Would a larger size be sufficiently wider?
